Problems solved by technology
[0002] At present, the commonly used rotary compensator has a large matching gap between the rotating parts, the overlapping part of the inner and outer guides is short, and the stability during rotation is poor. Due to the thrust of the pipeline, the relative rotation stability of the inner and outer tubes is poor, and it is easy to produce eccentric deflection of different axes. Increased rotational resistance, reduced flexibility for rotational compensation

Abstract
The invention discloses a wear-resisting type pipeline rotation compensator which comprises an inner rotation pipe, an outer sleeve, sealing filler and a connecting pipe. The inner wall of the middle of an inner hole of the outer sleeve is provided with an inner protruding ring. The outer wall of the right end of the inner rotation pipe is provided with an outer protruding ring. The left end face of the outer protruding ring of the inner rotation pipe is provided with an arc protruding ring with the axial section being an arc face. The end face of the right side of the inner protruding ring of the outer sleeve is provided with an annular groove with the axial section being an arc face. The arc protruding ring of the outer protruding ring of the inner rotation pipe is embedded into the annular groove in the end face of the right side of the inner protruding ring of the outer sleeve. A separation sleeve is arranged in the middle of the sealing filler and is in clearance fit with the inner hole of the outer sleeve and the outer wall of the inner rotation pipe. According to the further improvement, the arc radius of the surface of the arc protruding ring of the outer protruding ring of the inner rotation pipe is no larger than the arc radius of the surface of the annular groove in the end face of the right side of the inner protruding ring of the outer sleeve, and a wear-resisting and corrosion-resisting layer is arranged on the surface of the arc protruding ring of the outer protruding ring of the inner rotation pipe. The compensator rotates flexibly, and is good in rotating stability and wear resistance, high in corrosion resistance and long in service life.
Description
technical field [0001] The invention relates to a pipeline compensator, in particular to a rotary compensator. Background technique [0002] At present, the commonly used rotary compensator has a large matching gap between the rotating parts, the overlapping part of the inner and outer guides is short, and the stability during rotation is poor. Due to the thrust of the pipeline, the relative rotation stability of the inner and outer tubes is poor, and it is easy to produce eccentric deflection of different axes. Increased rotational resistance reduces the flexibility of rotational compensation. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes a wear-resistant pipeline rotation compensator with flexible rotation and good rotation stability. [0004] The present invention achieves technical goals through the following technical solutions. [0005] The wear-resistant pipeline rotary compensator includes a rotating inner ...
